View 3 Replies View RelatedMy ASA 5505 has stopped giving out DHCP address to my machines.Everything was working fine and nothing has changed in the network. I've reloaded the firewall and clear all DHCP on the firewall I've even re-entered the cmd on the ASA.
I'm able to staticlly assigned address to the clients and all is way. When I do a DHCP debug on the ASA I don't see any events relating to the DHCP service apart from checking for lease expiry.
I've also tried to plug a machine straight into the ASA and no result. I finally did a packet capture and I am seeing the client machine sending out a DHCP discover packet and nothing else is responding.
My ASA config is:
dhcpd address 192.168.3.10-192.168.3.33 inside
dhcpd dns 8.8.4.4 interface inside
dhcpd option 3 ip 192.168.3.1 interface inside

I have a 3911 router with a 1242 AP. The problem that I have is that when the user is trying to connect, the user get the OS Ip address 169.254.168.154 and I see that when I do the "show dot11 association" command, but when I do sh ip dhcp binding on the router I see
172.19.9.141 0100.18de.74db.14 Jan 31 2011 11:14 AM Automatic
The router is seeing as if the router gave the ip address to the user, but the reality the user was assigne the OS ip address 169. I did "debug ip dhcp server events" and I got the following:
Jan 31 11:09:06.752 EST: DHCPD: Seeing if there is an internally specified pool class:Jan 31 11:09:06.756 EST: DHCPD: htype 1 chaddr 0100.18de.74db.14

I have a RV042 router. The problem that I am having with it is that the DHCP is giving out the wrong Default Gateway and DNS Server. There is no option to change the DHCP server IP on any of the settings pages on the router. I am begining to think that there might not be a way to do it. I see that there is an option for the DNS under the DHCP page but the Public IP that is being handed out is not the one on that page. I also have 2 WAN connections hooked up as well a DSL link and a Cable link (the cable link is the primary one).
The following information is provided in an effort to resolve this issue:
IP of Router 10.0.0.2
IP of DHCP Server (the one that is being handed out):10.0.0.1
IP of DNS (the one that is being handed out): 10.0.0.11
What I want to it be.
IP of Router: 10.0.0.2
IP of DHCP 10.0.0.2
IP of DNS 10.0.0.2
So network was running fine for about a year or so. Network consists of 1 Motorola SB6120 cable modem attached to a D-Link DIR-601 wireless router. All settings were default except for SSID and WPA password. One day I just couldn't access internet anymore. I've narrowed it down to the default gateway that is being given out through DHCP. The default gateway that is being given out is the IP of the modem (192.168.100.1) and not of the Router (192.168.0.1). I can't find any option on Wireless router to be able to force the gateway address when handing out the gateway IP. Theoretically I thought I should be able to put router on same subnet as modem as 192.168.100.2 but that still doesn't work. If I set the IP adresses statically on the PCs and give it the Gateway of the Router everything works fine. I should mention this is for my boss' house and basically I dont want him calling me everytime he has a friend come over and I have to talk em through setting up a Static IP.
And just for an example this is what I get if I use DHCP:
IP Address: 192.168.0.155
Mask: 255.255.255.0
DNS: 192.168.0.1
Default Gateway: 192.168.100.1
And If I want it to work I have to change the default gateway to 192.168.0.1 I've tried updating routers firmware and reset to factory default numerous times. Is it possible for a router DHCP stop working?
I have a asa 5510 vpn client groups configured and connected to the internal network DHCP server stops giving network service dhcp and the network goes down.
View 6 Replies View Related I've came across IP address that aren't enough for some users in the company. The IP addresses are more than enough to cater to the user's notebook or PC. However, some users does not know that there are actually limits to the IP we have, so quite a number of them actually uses their mobile / pads to tap the company's wireless.
I was wondering if i could restrict that particular user from tapping onto the network. I know it sounds a bit impossible because DHCP doesnt have that smart function to block whoever we sees deemed as a "nuisance".
Up to today I used Verizoon 4G to a Windows Visata box running Internet connection Sharing to get my home lab connected to the Internet . All was working well.

I'm working in my lab trying to do proof of concept for traffic policing on the ASA 5510 running 8.0(4). I have two laptops running Ubuntu one on the outside and one on the inside. Both laptops have 100Mbps interfaces. My tests consists of downloading a file from one laptop using HTTP. Without any QoS I can see speeds close to 100Mbps which I would expect. On a side note, try using XP and you won't come close to those speeds. Anyhow, I implement policing using the config below and expect to see the max rate on the laptops during the transfer max out close to the CIR. However, I see speeds much higher on the laptops.
When I set the CIR to 10000 bps with bc at 1500 bytes I get speeds that range from 300Kbps to 700Kbps. I would expect to see speeds max out at the CIR which would be 10Kbps.I'm having a hard time understanding why my numbers don't match.
